１维护牵手行 共织动力网中国移动通信山东分公司艾默生开关电源维护速成宝典艾默生公司济南客户服务中心二零零五年九月２序 言中国移动通信责任有限公司山东分公司是艾默生网络能源有限公司极其重要客户和伙伴。
目前，山东移动网上运行的艾默生智能开关电源（包括前华为开关电源）共2800余套，其中，电源大部分型号集中分布如下：八期建设的由NP9801监控单元构成的PS48300-2/50，PS48450-2/50系统；九期建设的由PSM-A 构成的PS48400-2/50，PS48600-2/50系统；十期建设的PS48400-2B/50系统；十一期建设的的PS48400-2C/50系统；同时十二期正在建设中的基站电源也集中在由M500F 监控单元所组成的PS48400-3/2900和PS48600-3/2900系统。
此外，在早期基站中，还有部分由PSM-15组成的PS48100/25，PS48300/25，PS48120/20，PS48240/20系统。
以上型号的电源占到了目前总量的90%以上。
为了进一步加强山东省移动公司基层的维护技术力量，帮助贵公司提升网络质量，打造GSM 精品网络，共同提高移动公司市场竞争力，艾默生济南客户服务中心特组织精兵强将，以移动公司相对集中设备型号，编写了该维护手册。
本手册不仅包含了日常维护中80%以上的设备运行问题，同时，还介绍了电源日常保养、巡检和电源安装工程的内容和规范。
我们期待此手册能达到我们预期的目的，希望我们的服务能为贵公司在严峻的竞争中尽绵薄之力。
由于笔者水平有限，也恳请贵公司领导和同行们多指教！３１`第一篇：由NP9801构成系统日常维护指南（PS48300-2/50，PS48450-2/50）...................................................................................................................................... １问一：由NP9801监控单元组成系统的结构与配置情况？ ............................................... １ 问二：如果机房无三相电或有缺相时，电源的交流引入线如何连接？ ......................... １ 问三：整流模块前面板拨码开关是什么含义，如何设置？ ............................................. ２ 问四：模块地址如何设置？ ................................................................................................. ２ 问五：在更换该系统的整流模块时，有何注意事项，正确步骤？ ................................. ２ 问六：有时在开启模块输入空开后，模块打火或者后面开始冒烟？何故？如何处理？ ................................................................................................................................................ ３ 问七：当系统中其中一个模块无输出电流时，如何判断其好坏？ ................................. ３ 问八：模块间是否均流的判断标准是什么？当整流模块不均流时，如何调节？ ......... ３ 问九：为什么有时拆除一台整流模块，其他整流模块同时出现通信中断故障？ ......... ４ 问十：系统中单个模块通信中断，通常由那些因素造成，如何处理？ ......................... ４ 问十一：监控单元密码是多少？分别有什么用？ ............................................................. ４ 问十二：对于NP9801监控单元组成的系统，如何正确进行系统配置？ ....................... ４ 问十三：监控单元有集中复位方式？ ................................................................................. ５ 问十四：监控模块内需要设置的电池参数有哪些？ ......................................................... ５ 问十五：对于电池组数的设置，如果系统只有一组电池应该如何连接，监控模块如何设置？......................................................................................................................................... ５ 问十六：忘记用户级密码如何处理？ ................................................................................. ５ 问十七：防雷器部分如何维护？ ......................................................................................... ５ 附录：NP9801监控单元内目录结构如下： ........................................................................ ６ 第二篇：由PSM-A 构成系统维护指南（含PS48400-2/50，PS48600-2/50） ... ７问一：使用PSM-A 监控单元的型号有哪些？ ..................................................................... ７ 问二：交流接触器不吸合？ ................................................................................................. ７ 问三：交流接触器频繁跳动（吸合后随即断开）？ ......................................................... ７ 问四：交流防雷器故障告警？ ............................................................................................. ７ 问五：交直流通信异常？ ..................................................................................................... ７ 问六：交流电压正常，模块工作正常，但是负载不能够工作？ ..................................... ８ 问七：监控单元显示直流电流或电池电流与模块输出显示电流偏差很大？ ................. ８ 问八：负载熔丝断误告警？ ................................................................................................. ８ 问九：模块通信中断故障如何判断？如何处理？ ............................................................. ８ 问十：模块有输出电压，但没有输出电流？ ..................................................................... ９ 问十一：监控单元没有显示？ ............................................................................................. ９ 问十二：更换监控单元需要设置的数据？ ......................................................................... ９ 第三篇：PS48400-2B/50，PS48400-2C/50电源系统维护指南......................... １１问一：通常艾默生开关电源都由哪几部分组成？ ......................................................... １１ 问二：PS48400-2B/50系统交流配电部分由哪些部件组成？ ...................................... １１ 问三：移动十一期基站使用的PS48400-2C/50系统与十期基站的PS48400-2B/50系统有２何区别？在维护的时候有什么区别？ ............................................................................. １１ 问四：有哪些常见的交、直流保护参数？参照值为多大？ ......................................... １１ 问五：PS48400-2B/50系统的工作原理？ ...................................................................... １２ 问六：直流配电的基本特点？ ......................................................................................... １２ 问七：如果交流接触器不吸和，如何判断交流接触器的好坏？如何采取应急措施？ . １３问八：常见的模块故障有哪些，可能原因分析。
